OPTIMIZATION OF METHODS FOR MEASURING THE PHYSICAL AND MECHANICAL PROPERTIES OF COMPOSITE ELASTOMER POLYMER MATERIALS

Composite elastomer polymer materials are increasingly used in critical engineering applications, including mechanical engineering, aviation, energy systems, and medical devices, where high reliability and reproducibility of material properties are essential. However, existing methods for measuring their physical and mechanical properties often suffer from limited accuracy, insufficient repeatability, human-factor-related errors, and incomplete compliance with international standards. This paper presents a comprehensive optimization of measurement methods for determining tensile strength, elongation at break, hardness, and elastic properties of composite elastomer polymer materials. The proposed approach integrates standardized experimental conditions, advanced statistical analysis, and enhanced metrological support to ensure traceability and measurement reliability. A comparative analysis based on ISO 37:2017, ASTM D412, and ISO 48:2018 standards demonstrates that the optimized methodology improves measurement accuracy by up to 30%, significantly enhances repeatability, and reduces uncertainty. The results confirm that the proposed methodology is suitable for international laboratory comparisons and industrial quality control, contributing to the harmonization of national measurement practices with global metrological requirements.
